This invention relates to hose such as stockings manufactured in the correct form in a at hosiery knitting machine, the heel portions together with the instep portionconnecting them being prepared simultaneously, and to a method for manufacturing the same.

The invention applies more particularly to the method in which the heel portions which are to be manufactured simultaneously with the foot 10 portions are produced purpose of widening the heel portion, a1 certain number of the heel loops are widened in outward direction. Stockings thus prepared have hitherto exhibited in the vicinity of the heel, for instance below orbehind the ankle, some form of widening line which` on the one hand is unsightly and which, moreover, on the other hand, also detrimentally aifects the durability of the stocking, as the widening line is a line ofopen holes. y Another detrimental poin'tQis that the loops, located in the proximity of tlieqnfdening line are stretched in such a degree thaniractur of the needles and defects in the knitted web arise. The nished stocking itself does Anot t tothe human foot; there appear folds in the instep of the upper part of the foot,4 behind and above the ankle etc.

All these disadvantages are obviated in theH presentinvention, in that, for the purpose of widening the heel, the Widening is performed in a novel and characteristic way; namely, the widening is eiected only in the vicinity ofthe marginal loops, e. g. one or two marginal loops, whereby the widening can be securely sewn in with a proper marginal loop and is thereby made to disappear after the sewing.

How, after the heel has been widened in this manner, that is to say, after the desired size of the heel has been attained, `the heel rounding and narrowing is eiected is immaterial to the present invention. Thus, a few plain rows may be worked in immediate conjunction, orlo'ops may be cast oi, or narrowing may be eiected at l5 suitable points;

Some embodiments of the invention are shown lschematically by way of example in the accompanying drawings.

, Figure 1 shows the loop formation of a heel 0 portion in the case of two widened marginal loops and Figure 2 the loop formation in the case of one widened marginal loop. In Figures 3 to 10, four diierent stocking portions are schematin Figs. 3, 5, 7 and 9 as iiat ically shown at rst 5 articles as obtained while the machine is runin this way that, for the #of may be eiected in any the line lb-'b' ning, and then in Figs. 4, 6, 8and`10 in vside view as completed portions of the stocking.

It appears from Figure 1, ho'w,.after the leg has been completed as iar as `the row (1f-a', in every following row of loops two marginal loops 69 are widened in each side by as much as one needle, whereas according to Fig. 2, in every row only one marginal loop is widened by a'needle.

It is more advantageous for the purposer of vobtaining a good seam and iitting to perform the widening of two loops to the extent of one needle in each course. 'Ihe number of loops to be widened is preferably determined according to the'count of the material and the gauge of the machine. I v I 47 0 This widening of thema'rginal loops is effected until the desired heel widening or heel size has been attained. When the heel has been widened suiliciently, then, rounding and contracting theredesired manner, as has ,75

already been stated.

. In the following some examples of various heel lroundings and.narrowings are described.

According to Figs. 3 and 4 there is, after the completion of the leg, the heel widening, eiected 50 in the described manner from the line a-a to by stretching o'fthe marginal loops, whereby the knitted web is widened to the desired size of the heeland in immediate conjunction therewith a number of plain courses are worked up in order to obtain the correct rounding of the heel up to the line c-c'. '111e narrowing of the heel to the line' d-d is attained by narrowing, preferably in'every second course, whereby the narrowing line A-B is attained. V 99 According to Figs. 5 and 6,'the heel narrowing is so changed as to extend from the line c-c' to the line d-d', in which case the narrowing line is placed outwardly in the manner of heel cap narrowing (line CD).' There may 9.5

then take place, as is shownin Figs. 7 and 8, the

usual wedge shape narrowing., According to Figs. 9 and 10 the heel narrowing is attained by placing the narrowing line exact- 1y like thewidening line to the margin, so that-11.00

it disappears in the seam and no widening or narrowing lines of any sort appear in the heel.

A Whether with the heel rounding plain rows are worked depends upon the desired form of the heel. Instead of this kind of heel rounding and heel contracting by narrowingin any desired kind and at any desired pbce the shap of the lower part of the heel can be produced also by the casting off of loops, as has)already been stated, or in lany other manner. f l

,sewn in with a correct The essential feature ci.' the invention is the disposition of the widening line which can be line disappears rect form on a athosiery machine and having its heel portions made in one operation with the foot portion, widening loops connecting the heel .f portions and the foot portion and forming awidimmediately adjacent the marginal loops to be sewei in, a fewplain courses and thereafter a narrowing line lying in an oblique position' below the ankle and following said widening loops, said Widening within the inner portion of the seam.

3. A stocking manufactured in the correct form on a flat hosiery machine and having its heel porening line 'tions made in one operation with the foot portion,

widening loops connecting the heel portions and the foot portion 3and forming a widening line immediatelyr adjacent the marginal loops to be sewn in,'a few plain courses and thereafter a narrowing line lying in the heel cap portion of marginal loop into the` line 'being located the stocking and following -said widening loops, said widening line being located within the inner portion of the seam. f

4. In a stocking manufactured in the correct form on a fiat hosiery machine and having its heel portions made in one operation with the foot portion, widening loops connecting the heel portions and the foot portion and forming a widening line immediately adjacent theI marginal loops to be sewn in, and a narrowing line likewise lying in the range of the marginal loops and following said widening loops, said widening line being located within the inner portion of the seam.

5. The method of manufacturing stockings in the correct form on a at hosiery knitting machine, consisting in enlarging the heel by widening marginal loops located directly at the rim and adapted to be sewn in, and sewing said marginal loops with the widening line within the inner portion of the seam.

6. The method of manufacturing stockings in the correct form on a flat hosiery knitting machine, consisting in making the. heel portions in one voperation with thefoot portion, connecting them and effecting the connection of the' heel portions' with said foot portion byvwidening loops in such a manner that the widening line is located immediately adjacent to themarginal loops to be sewn in, and sewing said marginal loops with the widening line within the inner portion of the seam.
